The line “I’m Batman” is most strongly associated with Michael Keaton’s portrayal of Batman in Tim Burton’s 1989 film Batman. Over time, the quote became a long-running internet favorite because it is instantly recognizable, very short, and easy to drop into parody edits. It is still common in superhero memes, voice reenactments, and dramatic reveal videos, often alongside other recognizable reaction sounds such as the X files theme when creators want an exaggerated mysterious mood.
